A sampling system is disclosed which comprises a collection chamber equipped with an inlet and first and second outlets; a pump which creates a flow of fluid into said inlet from the ambient environment, wherein said collection chamber divides the flow of fluid into a first major flow of fluid along which flows along a first flow path between said inlet and said first outlet, and a second minor flow of fluid which flows along a second flow path between said inlet and said second outlet; a collection surface disposed within said collection chamber and within the second flow path such that particles in the flow of fluid into said inlet impinge on said collection surface; a heater which vaporizes particles that collect on said collection surface; and an analyzer which analyzes the composition of the fluidic flow through said second outlet.
